I am thinking THIS is the "halfway point"
Clean up the engine/ transmission/ transfer case
Pull the 5 speed install the new shaft and tail housing
Reinstall the 5 speed, add transfer case, investigate rear drive shaft
Install fuel tank
Ignore problems with front axle (needs brake work, may need tie rod/ other parts)
Get other hardware, brake tubes etc connected, re-string frame wiring harness
Consider fixing the alleged "deadly camshaft dowel pin" (I'm not sure that's a concern, really)
Consider installing the new lift pump I bought some time back
Reinstall cab, get it runnable and moveable regardless of front brakes, so I can move it on/ off the hoist
Reinstall bed and install front/ rear bumpers
Get 'er on the hoist and attack the needed front axle work (brakes wheel bearings seals, knuckle U joints, whatever) and complete brakes, bleed, etc.
Assuming I have come up with a rear driveshaft, inspect and replace needed U joints and center carrier bearing.
Deal with tires/ wheels, consider remounting old front tires on other wheels or buy ?? wheels and other tires??
